Cancellation Token is a pattern that allows us to refuse to continue calculations that we no longer need. It is implemented out of the box in many programming languages, for example in C# and in Go. However, there was still no sane implementation in Python, until the cantok library appeared.
Install it:
pip install cantok
And use:
from random import randint
from cantok import ConditionToken, CounterToken, TimeoutToken
token = ConditionToken(lambda: randint(1, 100_000) == 1984) + CounterToken(400_000, direct=False) + TimeoutToken(1)
counter = 0
while token:
counter += 1
print(counter)
